巩膜固定囊袋张力环联合超声乳化人工晶状体植入术治疗外伤性晶状体半脱位

Scleral-fixated capsular tension ring combined with phacoemulsification and intraocular lens implantation in the treatment of traumatic lens subluxation

摘要:

目的：探讨巩膜固定囊袋张力环(SFCTR)植入联合晶状体超声乳化吸除加人工晶状体(IOL)植入术治疗外伤性晶状体半脱位的临床疗效。

方法：连续选取2018-12/2023-02行SFCTR植入联合晶状体超声乳化吸除加IOL植入术治疗的外伤性晶状体半脱位患者14例14眼。术后随访行视力、眼压、眼前段照相、超声生物显微镜(UBM)等检查，并记录IOL的位置及术后并发症等情况。

结果：纳入患者均成功植入SFCTR和囊袋内IOL。术后平均随访1.92±1.36 a，末次随访时，UDVA(0.20±0.18 LogMAR)和CDVA(0.16±0.17 LogMAR)均较术前UDVA(1.13±0.56 LogMAR)显著改善(P<0.01)，眼压(17.64±3.67 mmHg)较术前(22.00±9.92 mmHg)降低(P<0.05)。随访期间，裂隙灯检查见IOL位于囊袋内，位置居中； UBM检查见CTR和IOL位于囊袋内，囊袋赤道部与睫状突的距离在各个方向相等。

结论：SFCTR植入联合晶状体超声乳化吸除加IOL植入术是治疗外伤性晶状体半脱位的一种微创有效的手术方法。

Abstract:

AIM: To investigate the effect of scleral-fixated capsular tension ring(SFCTR)combined with phacoemulsification and intraocular lens(IOL)implantation in the treatment of traumatic lens subluxation.

METHODS: A total of 14 patients(14 eyes)who underwent SFCTR combined with phacoemulsification and IOL implantation for traumatic lens subluxation from December 2018 to February 2023 were selected. Visual acuity, intraocular pressure, anterior segment photography, and ultrasound biomicroscopy(UBM)were examined during postoperative follow-up. The location of IOL and postoperative complications were recorded.

RESULTS: SFCTRs and IOLs were successfully implanted in all patients. The mean postoperative follow-up was 1.92±1.36 a. At the last follow-up, the uncorrected distance visual acuity(UDVA; 0.20±0.18 LogMAR)and corrected distance visual acuity(CDVA; 0.16±0.17 LogMAR)were significantly improved compared with the UDVA(1.13±0.56 LogMAR)preoperatively(P<0.01). The intraocular pressure(17.64±3.67 mmHg)was lower than that before the operation(22.00±9.92 mmHg; P<0.05). During the follow-up, the slit-lamp examination showed that the IOL was in the middle of the pouch. UBM examination showed that the CTR and IOL were located in the pouch, and the distance between the equatorial part of the pouch and the ciliary process was equal in all directions.

CONCLUSION: The SFCTR combined with phacoemulsification and IOL implantation is an efficient and minimally invasive method in the treatment of traumatic lens subluxation.
